go up there with buck

After you capture/defeat heatran they start roaming sinnoh
in the sinnoh pokedex u dont need to c heatran he is only obtainable after u get the national dex
You don't have to see Heatran in order to complete it.
heatran lives in stark mountan
Pokemon that are from the sinnoh, hoenn, kanto, johto
Heatran is a Fire and Steel type pokemon.
need to see all Pokemon that you can see in the sinnoh region (216) and then speak to the professor and he'll give you the national dex.after that u can catch lagandarys like heatran regigigas...;)
aggron is weaker than heatran by a mile simply because heatran is a legendary Pokemon
To find or catch Heatran, you need to have already finished the Stark Mountain quest which is available after you defeated the Sinnoh Elite Four and got the National Pokedex. Where Charon and the Team Galactic Grunts were captured by Looker and the International Police, Heatran will be there. Heatran will be level 50 and have he following moves: Metal Sound Crunch Scary Face Lava Plume
other lakes then sunnyshore city then pokemon leauge then see all sinnoh pokemon get national dex then go catch heatran get action replay GET DARKRAI
The Pokemon tamed by the Magma Stone is Heatran, HOWEVER you need to see all 210 Pokemon in that Region. Now how I did this was on R4, (Revolution For DS) so you'd be awfully lucky to complete the National and the Sinnoh Dexs.
